2.个体，作为一个不可分割的整体存在的事物，或作为一个
类别
3.类型，其他集合或类的一组个体或类。
4.元组，事物的有序位置（例如，电子表格或表格中的块）。
这些基础元素类似于许多其他基础数据结构
存在于该行业中。可重用的常见模式有：
1.组成（或全部或部分）。
2.超级/子类型（或一般化/专业化，如坦克或主战坦克）。
3.之前/之后，对于类型中具有时间相关关系的事物。
4.重叠，例如，对于可以交换作为自身一部分的其他事物的事物，
发生在重叠时间和重叠地点的事情。
组合和超级/子类型适用于几乎所有的架构概念。前/后是
经常用于建模前/后情况，而接口适用于少数概念，

DM2——DoDAF概念数据模型
http://cio-nii.defense.gov/sites/dodaf20/conceptual4.html[2011年3月3日下午3:46:40]
采用正式基础和通用模式的想法的好处是：
1.重复使用常用模式节省了大量工作
2.通过继承超类属性和公共模式来建模紧凑性
3.对账和分析工具。商定的分析原则提供了
问题分析的原则基础
4.信息谱系模型
5.设计具体化和需求可追溯性
6.服务说明
7.语义性。提高了集成和分析多种异构数据的能力
实现EA目的的EA数据集。
8.数学精度
DM2物理交换规范描述中详细描述了这些好处

服务：允许访问一组一个或多个功能的机制，
其中使用规定的接口提供访问并进行访问
与服务描述中指定的约束和策略一致。
机械装置是一个执行器。访问的“能力”是资源--
信息、数据、物资、表演者和地缘政治范围。
项目：响应愿景、目标和
旨在改变某些情况状态的目标。临时的

hing, similar to other model’s object.
2. Individual, a thing that exists as an indivisible whole, or as a single member of a
category.
3. Type, a set of individuals or classes of other sets or classes.
4. Tuple, ordered places of things (e.g., a block in a spreadsheet or a table).
These foundation elements are similar to many other foundation high-level data constructs
that exist in the industry. The common patterns that are reused are:
1. Composition (or whole-part).
2. Super/Sub Type (or generalization/specialization, e.g., tank or main battle tank).
3. Before /After, for things that have time-related relationships in their Type.
4. Overlap, e.g., for things that can exchange other things that are parts of themselves,
things that occur at overlapping times and overlapping places.
Composition and Super/Sub Type apply to almost all architecture concepts. Before/After is
frequently used to model before/after situations, while Interface applies to few concepts,
limited at this time to the pattern describing Activity.

DM2 - The DoDAF Conceptual Data Model
http://cio-nii.defense.gov/sites/dodaf20/conceptual4.html[3/3/2011 3:46:40 PM]
The benefits of adopting the IDEAS formal foundation and common patterns are:
1. Re-use of common patterns saved a lot of work
2. Model compactness through inheritance of superclass properties and common patterns
3. Reconciliation and analysis tool. The agreed-upon analysis principles provide a
principled basis for issue analysis
4. Information pedigree model
5. Design reification and requirements traceability
6. Services description
7. Semantic precision. Improved ability to integrate and analyze multiple heterogeneous
EA datasets to fulfill EA purposes.
8. Mathematical precision
These benefits are described in detail in the DM2 Physical Exchange Specification description
documents.

Presentation Types for DM2 Data
DM2 Data Groups
For ease of understanding; the DM2 LDM is presented in groups of semantically related
concepts into clusters. These clusters are categorized as Principle Architectural Constructs
and Supporting Architectural Constructs. The Principle Architectural Constructs are the
fundamental building blocks necessary to describe an enterprise's internal and external
behavior and structure. These are as follows:
Performers: Any entity - human, automated, or any aggregation of human
and/or automated - that performs an activity and provides a capability.
Resource Flows: The behavioral and structural representation of the interactions
between Activities (which are performed by Performers) that is both temporal
and results in the flow or exchange of objects such as information, data,
materiel, and performers.
Information and Data: Representations (descriptions) of things of interest and
necessary for the conduct of activities. Information is the state of a something
of interest that is materialized -- in any medium or form -- and communicated
or received.
Rules: How rules, standards, agreements, constraints, and regulations and are
relevant to architectures. A principle or condition that governs behavior; a
prescribed guide for conduct or action
Goals: How goals, visions, objectives, and effects relate and bear on
architectures. A desired state of a Resource
Capability: The ability to achieve a Desired Effect under specified [performance]
standards and conditions through combinations of ways and means [activities
and resources] to perform a set of activities.
Services: A mechanism to enable access to a set of one or more capabilities ,
where the access is provided using a prescribed interface and is exercised
consistent with constraints and policies as specified by the service description.
The mechanism is a Performer. The "capabilities" accessed are Resources --
Information, Data, Materiel, Performers, and Geo-political Extents.
Project: All forms of planned activities that are responsive to visions, goals, and
objectives that aim to change the state of some situation. A temporary
endeavor undertaken to create Resources or Desired Effects.
Reification: The process of reifying or to regard (something abstract) as a
